Why would SMSL release another THX headphone amplifier?yes would like to know
Seems SMSL are moving away from THX for new products, although THX amps still available for now
SMSL already has the SH-9 as an SE and the SP-400 as a balanced amplifier, both with relay based volume control and remote control. The SP-400 can also be used as a preamplifier. Both devices are based on the highest design level THX AAA-888.
